    Default Which one?



    Ok folks, another "which one" thread. On my SW 120 ED, I have a Baader Hyperion 24mm and its so-so, not so great at the edge in my eyes. I very much enjoyed the view of a 27mm Panoptic I was lucky enough to try. I also recently got a ES 82* 14mm ep and think the ES series is just wonderful. What I'm asking is would you rather have a 28mm ES 68* or a 24mm ES 82*, and go!

    I have the ES 20 mm and will be getting the ES 82 6.7mm soon, but I don't have those specific EPs. I am going to bet that most people will like the 82* over the 68*. However, IMHO there are two practical issues.

    One there is a $90 difference in price which is nothing to sneeze at. Not all 82* are higher priced than the 68*, but these two are. Second, the 82* is a 2 in barrel and the 68* is a 1.25 in. If you are in to filters, this can run you up on costs as 2 in filters are usually 2x the cost of a 1.25 in filter. Not to mention focal extenders might be wanted/needed for both barrel sizes as well, depending on the EP mix. So this can be a hidden cost in 2 in EPs or worse, mixing 1.25 with 2 in within the same set, maybe needing or at least wanting filters/focal extenders in both sizes.

    In practical terms, you will likely run into the need for 1.25 in and 2 in EPs once you get above the 20-24MM FL and into higher quality EPs. I tried to find all 1.25 in or even all 2 in EPs for 5-6mm through 28MM and really couldn't for the quality I wanted. So I am in the position of getting filters for both sizes and likely an 2 in focal extender along with the 1.25 in I already have.

    Now all that said, the 82 EP is going to give you a wider AFOV and better views in general. It is a bit of personal preference as well as budget issues (where such cost issue exist between the two EPs) as to whether one a better value over the other.

    Never tried the 68°, but I absolutely love my 82° 24mm. Of course, this (tonight) is only my second night of use, but I could just sit and pan around the sky with this eyepiece and thoroughly enjoy myself. The FOV is generous, bright, and the stars are sharp pinpoints across the field. It's a wonderful EP in my opinion. I like it!

    I have most of the ES 82s including the 24mm and a few of the 68s but not the 28mm, because I have the 24. I have the 68s because some of my scopes only have a 1.25" focuser so I actually have the 24mm 68 as well as the 24mm 82, so I have quite a bit of experience with the ES EPs on several different scopes. I say you can't go wrong either way. Slightly more magnification and field of view with the 82 for more expense but you will be satisfied either way you go.

    I LOVE my 68° 20 mm EP. I use it all the time and think it is highly underrated. The 68° FOV is very natural and the stars are nice and crisp from edge to edge.
